DSIP vs Carnosine
Side-by-side comparison of key properties, dosing, and research.
- Summary
- DSIP is an endogenous neuropeptide originally isolated from rabbit cerebrospinal fluid that induces delta-wave (deep) sleep. It also modulates stress response, cortisol regulation, and LH secretion, making it valuable for sleep optimization and stress management.
- Carnosine is an endogenous dipeptide (beta-alanine + histidine) found in high concentrations in muscle and brain. It is a potent anti-aging molecule with broad spectrum antioxidant, anti-glycation, anti-carbonylation, and metal chelating properties, making it one of the most protective naturally occurring dipeptides.
- Half-Life
- ~30–60 minutes; however downstream sleep effects last 4–6 hours
- ~1.5 minutes (rapidly hydrolyzed to beta-alanine and histidine by carnosinase in blood; tissue levels maintained via constant synthesis)
- Admin Route
- SubQ, IV, Intranasal
- Oral, Topical
